Use wildcards in tag values to retrieve multiple series from the server instead of defining separate series for each tag in the widget configuration.

Specify the * wildcard as either tag value or entity name.

  entity = nurswgvml007
  metric = disk_used_percent
      mount_point = *

Reference wildcard series from derived series using an alias.

Wildcard series are supported in all widgets including Bar Charts which provide a multiple-column setting to place derived series with the same entity and tags into separate columns.
